Common Solution Heat Treat Process Definitions
|
Process Definitions courtesy of ASM International :
Solution Heat Treatment is
heating an alloy to a suitable temperature, holding at that
temperature long enough to cause one or more constituents to
enter into solid solution, and then cooling rapidly enough to
hold these constituents in solution.
Precipitation Hardening is
hardening caused by the precipitation of a constituent from a
supersaturated solid solution.
Aging is a change in the properties of certain metals and alloys
that occurs at ambient or moderately elevated temperatures after
hot working or a heat treatment or after a cold working
operation. The change in properties is often, but not
always, due to a phase change (precipitation), but never involves
a change in chemical composition of the metal or alloy.
Artificial
aging is aging above room temperature. |
